After reports of a dangerous gas being emitted from several suburban industrial sites, U.S. Sen. Tammy Duckworth and other lawmakers have introduced a bill that would force the EPA to more quickly disclose similar public health risks.

A new analysis shows that closing Chicago's final two vehicle emissions testing facilities came at a cost to hundreds of thousands of city drivers, with the biggest impact on low-income and minority drivers.

Soil samples have been collected from more than 100 properties as the U.S. Environmental Protection Agency continues to assess the threat posed by brain-damaging manganese emitted from nearby industrial sites.

Local public health experts are set to testify at a Chicago hearing next week on the Trump administration’s proposal to repeal the Clean Power Plan, which established limits on pollution from power plants.

Former EPA chief Scott Pruitt said his proposal would increase transparency, but opponents say it will keep certain scientific studies out of the hands of EPA decision-makers and addresses “a ‘problem’ that does not exist.”

In a joint statement released Thursday, attorneys general from nearly 20 states, including Illinois, said weakening the so-called clean car rules would cause Americans to breathe dirtier air and pay higher gas prices.
